IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 39,528, dated August11, 1863.

ro n whom it may concern: V

Beitknown that I, CHARLES W. S. HEATON, of Salem, in the county ofMarion and State of Illinois, have invented certain new and usefulImprovements in Cultivators; and I do hereby declare that the followingis a full, clear,

and exact description thereof, reference being had tothe accompanyingdrawings, making a part of this specification, in which- A Figure 1 is aperspective view of my im-' proved cultivator complete. Fig. 2 is abottom view fof the front part of the frame and beam, showing the mannerof bracing the same. Fig. 3 is a side view of Fig. 2. Fig. 4. shows thecurved braces and shovel standards or stocks;

Similar letters of reference indicate correpon'di'ng" parts in theseveral figures.

My invention relates to certain improvements in constructing and arrangin g the several parts of an adjustable cultivator, whereby lightnesswith great strength are obtained and an improved agricultural implementis made at slight cost.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. I

The frame of this machine consists of three longitudinal parallel beams,A B B, and two transverse tarmac O. The central beam, A, being muchlonger than the twoside beams, B B,- it may be termed, for reference, adraftbeam, although it will be seen from the following description thatthis beam is merely intended as a support for draft-rods which take theplace of the draft-beam. The two side shovel-supporting beams, B B, areconnected by means of vertical bolts a to transverse beams G O, which,being slotted, as shown in Fig. 1, allow the side beams to be adjustedlaterally and set by means of the nuts on bolts a at any desired point.These transverse slotted supports 0 G are arranged, one, (3, below thecentral beam, A, and the other, C, on top of this beam. The longitudinalbeams B B are therefore supported at their forward ends upon one of thetransverse beams and at their rear ends below the other cross-beam, bothof which beams are bolted at the middle of their length to the centralbeam by means of vertical through-bolts.

The central beam, A, extends out beyond the cross-beam 0 some distance,and near its forward end an oblong hole is made transversely throughthis beam, as shown at 0, Figs. 1, 2,

and 3, through which hole is passed a bolt or clevis-pin, d, to the endsof which the horizorital cle'vis g is connected. Two rods, h h, are alsoconnected at their forward ends to the clevis-pin, and these rods arerigidly fixed at their rear ends to the extreme ends of the forwardcross-beam, O, as shown in Figs. 1, 2, and

3. Now, it will be seen that the brace-rods h h, beingconnected to theclevis-pin, and. this pin being loosely passed through a hole in thecentral beam, these rods are really the draftrods and bring the draftupon the cross-beam G. The clevis-hole 0 being elongated vertically, thepin it is allowed afree rising-and-falL in g motion in this direction,restrained only by the depth of this hole 0.

Beneath the central beam, A, and connected to its extreme front end byavertical bolt, 2', is a brace-rod, 7c, the rear end of which is connected to the vertical bolt in, which secures the cross-beam C to beamA. This latter brace rod isnot connected to the draft-rods, but isintended as a brace for the central beam, A,

and can only be practically used when' the cross-beam G is placedbeneath the beam A.

The rear end of central beam,- A,projec'ts out a short distance behindthe elevated cross-beam O, and at this end a plow or shovel, E, may beattached, the stock E of which is secured on one side of the beam A,behind the crossiece C, while the inclined brace-rod F is secured on theopposite side of beam A, in front of'this cross-piece, as shown inFig. 1. In this manner the stocks or standards of the forward shovels, GG, and also the inclined braces of these stocks, are secured to theirrespective beams B B.

The stock E of the middle shovel, E, Fig. 4, is curved, so as to bringthis shovel directly under and in the same vertical plane with thecentral beam, A. The brace F of this stock is also curved in a similarmanner and attached to the lower part of the stock E. In this way bothbars E and F mutually brace each other in a lateral direction andstifl'en each other, forming what may he called a V-shaped brace for theshovel E, consisting of two pivoted arms secured on opposite sides ofthe central beam, A,by means of transverse bolts p p. The beams A BB areperforated, and so also are the shovel stocks and braces, to admit ofthe shovels being arranged in different positions, adjusted at anydesired inclination, 850., according to the character of the crop it isdesired to work.

The handles H H incline forward, and are attached at their front ends tothe sides of the central beam by means of staples. The rear support forthese handles is a bifurcated standard, J, which is bolted to thecross-beam G and central beam,A, by abolt passing through both beams.The upper ends of the standard J are perforated and receive a horizontaltransverse brace-rod, s, which passes through the handles H, and hasconnected to its ends the vertical brace-rods t t, which are connectedat their lower ends to the extreme ends of the elevated beam 0, thussupporting this beam 0 at its ends and adding great strength to it. Fromthis description it will be seen that the rods h h and it serve asbraces for the crossbeam 0, and as deflectors to prevent the corn orother crop from being thrown down under the shovels, and also, by meansof the large hole 0, they act as draft-rods, the whole draft or strainbeing thrown by them on to the front crossbeam, 0, making it really thedraft-beam, and throwing an equal draft on all the beams, which are thuspulled equally. The only time when an unequal strain can come on thecenter beam, A, is when the middle shovel, E, is in front of the sideshovels and meets with any root, stone, or other resistance,when thedraft would have a tendency to break the beam at the bolt-hole m. Thisis provided against by the rod ormartingale 70, which is connected tothe bolt m and also to the front end of this central beam, A; and whensuch strain occurs the bolt i prevents the beam from splitting at thelarge hole a, as it would otherwise do, theinvariable tendency being tothrust the clevis up and the beam down when the shovels strike. Theclevis g being arranged horizontally instead of vertically, thevibratory motion of the trace produced by the step of the horse is notcommunicatedto the beam A, as the clevis rides loosely inits hole 0 onits bolt 01, which passes through thishole, but does not touch the beamA, being held in position by the two rods h h, and not by this beam,which only serves as a guide in my cultivator.

I am aware that in my patent of the 12th of March, 1861, two diagonal oroblique bracerods are arranged upon the cultivator-frame in such amanner as to brace the frame and the tongue of the cultivator; but thereis no third brace, nor is there a vertical slot and vertically-shiftingclevis pin or bolt.

Iam further aware that in the patent granted to E. Bcment, September 16,1862, on a plowbeam, two brace-rods are arranged so as to bear thestrain; but in this the clevis pin or bolt plays in a longitudinal slotin the direction of the pull by the team, and there is no third bracenor ayertical slot, as I show in my present cultivator.

I do not here claim, therefore, the braces as shown in my patent abovereferred to, nor do I claim the arrangement shown in Bements plow; but

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The arrangement, infa cultivator, of the brace-rods I]. h andstay-rod k in such manner that the longitudinal strain upon theimplement shall be thrown upon the side beams, B B, and front beam, G,when the implement is unobstructed by stones, 8220.; but when theimplement is obstructed by stones, &c., the sudden jar due upon thetongueA shall be relieved by the oblong slot 0, and finally be sustainedby the stay-rod 7c, all substantially in.

the manner set forth.

2. The arrangement, in a cultivator, of the automatically shiftin gbrace-rods 71, i h, pin d, and vertical slot 0, in the manner and forthepurpose described.

3. The arrangement of the inclined stay-rod.

k, beam 0, and tongue A, substantially as and for the purpose set forth.

4. A cultivator combining in its construction the tongue A, side beams,B B, upper and under slotted cross-beams, O O, V-shaped adv justablebraces or stocks E E, brace-rods h h, and stay-rod 7c, the several partsbeing con structed and arranged as described.

' Witness my hand and seal, in the matter of my application for patenton improvements in or on my cultivator patented March 12, 1861, this20th day of January, 1863.
